The field experiment was carried out at the Experimental Station of Vytautas Magnus University Agriculture Academy (Lithuania) in 2017–2019. aim study to determine and compare weed spread caraway crop productivity sole (spring barley, spring wheat, pea, caraway), binary barley-caraway, wheat-caraway, pea-caraway) trinary barley-caraway-white clover, wheat-caraway-white pea-caraway-white clover)...
10 The dry and wet deposition of radionuclides released into the atmosphere can be 11 intercepted by vegetation in terrestrial ecosystems. The aim of this study was to quantify the 12 interception of wet deposited Cs and Sr by spring oilseed rape (Brassíca napus L.) and 13 spring wheat (Tríticum aestívum L.). The dependency of the intercepted fraction (f) on total 14 above ground plant biomass,...
The winter wheat/summer fallow rotation is the most common cropping system in eastern Oregon. It is used to store winter precipitation and control weeds. This cropping system, however, destroys soil organic carbon, reduces water infiltration and thus leads to soil erosion, and is not sustainable. Conservation tillage, annual cropping, and the introduction of alternative crops are ways to improv...
of Research Findings The project has now completed two crop-years of experimentation. Four more crop-years are required for all crop rotations to complete a full cycle. This report covers the 2004-05 cropyear results. CBARC experiment (Moro): Grain yields of winter wheat following fallow (conventional or chemical) produced significantly higher yields than yields of annual cropping systems invol...
Large unheated greenhouse areas are located in the coastal lands of the Mediterranean Basin, based on low-cost structures covered with plastic. Water is a scarce resource in these areas and therefore it is necessary to optimise irrigation practice by applying the crop water needs, thus avoiding waste. This work was undertaken to determine the water requirements of four major horticultural crops...
in order to evaluate the effects of cover crops on reduced weed biomass in hybrid sunflower an experiment was carried in the research stations, natural resources medicinal plants (samian_ardabile) with 3 replicates in 1390-1391. the first factor was considered three type of cover crops, winter rye, spring barley, winter wheat with 2 control treatment, second factor was mulch management at two l...
to study the root allelopathic effects of cool season crops on germination and early growth of three crops (sorghum, corn, and soybean), an experiment was conducted in seed research laboratory and greenhouse of college of agriculture, university of tehran. the experiment consisted of four cool season crops (wheat, barley, rye and pea) and control as the main plots, three spring-crops (corn, soy...
Rapid changes in practices used to produce perennial grass seed crops in the U.S. Pacific Northwest region and shortened lengths of time that perennial grass seed fields remain in production have increased the need for additional rotation crops that are adapted to the poorly drained soils found in western Oregon. This research was conducted at three sites to determine ways to manage meadowfoam ...

The effects of applied digested pig slurry on a vegetable crops field were studied. The study included a 3-year investigation on nutrient characteristics, heavy metals contamination and hygienic risks of a vegetable crops field in Wuhan, China. The results showed that, after anaerobic digestion, abundant N, P and K remained in the digested pig slurry while fecal coliforms, ascaris eggs, schisto...
